Buleryan is a very unusual-looking stove that can solve the heating problem once and for all country house, garage, greenhouse and any other room. It provides quick warm-up with minimal fuel consumption, which can significantly save time and money. This pleasure is quite expensive, but if you like to work with your hands and are not afraid of difficulties, it is quite possible to make a Buleryan oven with your own hands.
This unusual stove has found application in many areas. So, it can be used not only for heating residential premises, greenhouses, garages and workshops. IN European countries Buleryan is used to warm up saunas and baths! This is a pretty good hybrid of the good old potbelly stove with a wood stove long burning. The operation of the device is based on forced convection. A series of arched pipes at the top and bottom lead into the firebox. Cold air circulates in the lower openings, which, passing through the firebox, quickly heats up and exits through the upper openings. This way the room warms up quickly. The temperature that is formed during the operation of the buleryan is so high that it can easily warm up even a small two-story house. In addition, it is possible to combine the stove with a water heating circuit, receiving double benefits - warm house And hot water. We will talk about water heating with Buleryan a little later, but for now we will look at the design of the stove in more detail. Buleryan is capable of functioning in two modes. First, the stove heats up quickly and distributes heat evenly throughout the room, and then goes into slow combustion mode. At first, you will have to add fuel quite often, but only to properly warm up the buleryan. When this happens, the firebox can be “fed” only twice a day. When the firewood is completely burned in the combustion part, the combustion products move through the convection pipes to the secondary combustion compartment, where the air-gas mixture is burned at an extremely high temperature. As a result, the efficiency of the device is at least 80%. A visual principle of how the Buleryan works can be seen in the video below:
If you intend to collect buleryan with your own hands, we must warn you - this is not an easy task. Besides professional skills welding you will need a lot special equipment and a wagon of patience. Be prepared for the fact that such a stove cannot be built in one day, and you will have to tinker. Some parts can be ordered from a locksmith shop, others can be purchased ready-made. The furnace was based on the design of a convection air boiler or simply a heater. The wide firebox door must be completely sealed. A blower pipe with a throttle passes through it, which regulates the power. Sometimes the throttle handle is equipped with a special temperature scale with a limiting stop so that the stove does not overheat. If necessary, the throttle can be closed to extinguish or suppress draft.
To increase the efficiency and performance of the buleryan, it is necessary to carefully insulate the chimney. Most often, inexpensive mineral wool is used for this, laid in a layer at least 3 mm thick. You will also need to build a vent to allow air to enter the firebox. You can also organize an ash pit just in case, but such a stove leaves virtually no waste. Thanks to the double rear wall, work efficiency is enhanced. In some models you can see a two-layer casing. Making a furnaceWe remind you once again that the manufacture and installation of buleryan in a house can only be done by experienced welders, so if you are unsure of your abilities, it is better not to take risks and buy a ready-made structure. First of all, prepare detailed diagram buleryan. At the end of the article you will find clear example and you can use it as a basis for building your own stove, changing the dimensions if necessary. What tools will you need first:
With the material the situation is more complicated. The first priority is to find quality steel that can withstand prolonged exposure to extremely high temperatures. Boiler steel is not so easy to get nowadays, but if there is such an opportunity, it will be the best option for buleryan.
Materials for the construction of the furnace:
How to make buleryan:
You can use an ordinary old boiler as the basis for buleryan. It will make excellent walls. This way you will save yourself from a lot of welds. However, the option outlined above looks more aesthetically pleasing than a barrel surrounded by tubes. It is also worth mentioning how to choose the dimensions of the stove in accordance with the area of the room that needs to be heated. Focus on the technical characteristics of the power and the rate of heating of the air volume per minute. Thus, the heating rate of a buleryan with a 40 liter firebox is about 4.5 m³/min. Accordingly, if you increase the volume of the firebox by 10 liters, that is, up to 50 liters, then the heating rate will increase to 9 m³/min. A stove with a firebox of 100 liters will warm up 18 m³ of air per minute. Safety precautionsIt would be useful to mention safety precautions when using buleryan. The structure of this stove is quite complicated if you understand it, but anyone can learn how to use it. One of the requirements of Canadian lumberjacks for heating stove There was fire safety, but nevertheless, when dealing with fire, it is almost impossible to reduce the risk to zero. The Buleryan stove should be installed at a distance of at least 40 cm from the walls of the house. It is recommended to place the device on a small hill - this will increase draft and reduce the risk of fire. As a rule, a special metal podium is built under it, and sheet steel is laid under the firebox so that sparks or stray embers do not burn the floor. Review of the Buleryan stove in video format:
Water buleryanAs we promised, it’s time to talk about water buleryan. Indeed, why not adapt such an excellent design for water heating? Such models are already commercially available, but their effectiveness and feasibility leave much to be desired. As one famous submarine designer said: “This is a vivid example of the victory of technology over common sense.” Manufacturers of such “vodobuleryans” either did not study physics at school, or forget about the basic principles of operation and the original purpose of the design - heating the air. Air and water are completely different matter with different characteristics heat capacity. So, for water this indicator is 800 times higher than for air, therefore, it needs more energy or more time to heat up properly. The design of the Buleryan with side heating is unable to do this, even if it wants to.
And yet there is a way to heat water in a buleryan for heating - to make the combustion in the firebox more intense. However, the efficiency will be significantly lower. If this fact does not scare you, let’s briefly consider how to adapt an air buleryan for water heating. For example, we have 2 batteries, each with 4 pipes, and the furnace power is 10 kW. With intensive combustion, the air in such a furnace will heat up by a maximum of 160°. By putting ordinary metal corrugations on two pipes and connecting them to the pipes passing through the firebox, we get a water heating device. It makes no difference whether these pipes are installed vertically or horizontally. Water will take 2.5 kW. If the volume of the firebox is 80-100 liters, and this compartment is insulated with two layers of steel, then in half an hour the Buleryan will heat the water to 60-70C, and this temperature will be maintained subsequently. Compared to regular electric boilers, then heating element heating consumes from 3.5 to 5 kW.
Buleryan: photoYou can use these drawings of the Buleryan as a basis for building a structure with original dimensions. This is a small stove designed for heating garages, greenhouses and workshops. If you want to make a stove for your home, increase the dimensions by 1.5 times or more.

Announcement: The article will help you understand the difficulties of making Buleryan with your own hands from various materials: profile or round pipe, gas cylinder, metal sheets. It also discusses the basic rules for operating long-term combustion furnaces.
Construction of the future stove
The Buleryan stove, also called the Breneran stove, is a solid fuel heating system that is simple to implement: it can be assembled by anyone who is familiar with metal material and knows its basic properties. Of course, working with iron requires a certain amount of care, unlike wood and concrete materials.
This type of stove involves a gas-generating type of wood combustion, that is, combustion products emit pyrolysis, which is sent to the afterburning chamber and, together with secondary air, is completely burned out. The final combustion product is sent through the chimney to open air, leaving behind condensation.
The design of the Buleryan stove consists of several parts:
- The combustion chamber is the most spacious part of the stove, it works as the main combustion chamber for wood, which is placed on convection pipes;
- Afterburner - a sheet of iron that separates the upper quarter from the general chamber; combustion products burn out in this part;
- Pipe convector is a part of a device made of several curved pipes that are in direct contact with combustion products (wood, coal, gases);
- Loading door solid fuel– with the help of this part of the design it is possible to load firewood, it also regulates the amount of oxygen supplied into the system;
- The chimney is the part of the furnace responsible for collecting condensate and leaving the final combustion products outside the system.
- Injectors - tubes responsible for supplying secondary air;
Such a simple design of this heating system has made the Buleryan stove very popular among those who like to make various designs with their own hands. The simple principle of operation, ease of manufacture and efficiency of the system also contributed to the widespread use of this furnace.
Manufacturing options
Today, two options for manufacturing the Buleryan stove are known, based on the materials they are made from: from profile and curved pipes or from a gas cylinder. Each type of system has its own efficiency and varies in implementation complexity:
- From a profile pipe. The Buleryan system made from a profile pipe is a simple design that provides efficient heating of small spaces: a garage, greenhouse, barn or small gym. The stove is easy to manufacture and can be made by any welder from scrap materials.
- From a gas cylinder. Due to the fact that almost every private yard has an old gas cylinder, this type of stove is manufactured quite often. Perfect solution for a country house or garage, and thanks to the shape of the cylinder, it becomes possible to implement interesting design ideas.
The Buleryan stove is easy to make with your own hands, no matter what type you decide to make yourself. The choice depends on the capabilities of the master, the availability of material and the skills of the owner.
Buleryan from a profile pipe
For the manufacture of the structure, profile pipes measuring 6 by 4 centimeters are suitable; it is with this diameter that the round pipes were installed in the original stove. The thickness of the metal in the pipes is at least 3 mm. A larger diameter will require copious amounts of firewood to heat the room and will cause a decrease in Heating efficiency systems. To make the frame, you can use iron sheets 5 mm thick. The method of manufacturing a structure from a profile is completely identical to manufacturing the same system from round pipes.
Scheme and drawing
When welding a heating system, you can either bend it or weld it from blanks; the main thing is to respect the general structure of the stove so that it works correctly. Below is a diagram of the Buleryan furnace in a section made of round metal pipes, instead of which you can use profile.
This type of design involves the use of curved blanks, which simplifies the assembly of the whole system, but complicates the manufacture of the blanks themselves, since not every owner is able to bend profile pipes.
Materials
To make a Buleryan stove, the following materials are required:
- Profile pipes measuring 60x40 mm, metal thickness 3 mm, 7 pieces;
- Sheets of iron 5 mm thick for covering the skeleton of the structure;
- Iron sheet for the partition in front of the chimney, 3-6 mm thick;
- The pipe section for the chimney is at least 120 mm;
- Metal materials for the door, front wall, back wall (sheets, handle, round pipe);
You can additionally add various parts in outer part systems so that the stove visually acquires a more aesthetic appearance.
Tools
For successful and convenient work you need the following tools:
- Grinder and metal wheels;
- Welding machine;
- Measuring instruments – square, tape measure, ruler;
- Pipe bender - if necessary;
- Marker for marking.
Step-by-step instruction
Design example
For a clear understanding, you can watch this video, which tells you step by step how to make Buleryan with your own hands, with the indicated dimensions of all its parts:
An excellent DIY design is demonstrated in this video:
Do not forget that the structures must be installed at a height of at least 15 centimeters from the floor, for effective air circulation and increased efficiency.
Buleryan from a gas cylinder
You can simplify the manufacturing process if you use an old gas cylinder as the main combustion chamber:
Gas cylinder construction
If you understand the meaning of the operation of a long-burning fuel stove, then in the manufacture of buleryans you can use not only a cylinder, but also other available materials for the production of metal structures.
Scheme and drawing, dimensions
Essentially, a homemade Buleryan stove from a gas cylinder is made in the same way as a long-term combustion stove from iron sheets, but the difference is that the main combustion chamber is already ready and does not need to be made from scratch.
The drawing above shows the design diagram in detail, indicating all dimensions. Take them into account in order to properly make a Buleryan stove with your own hands.
Materials
In addition to the gas cylinder, you will need round or profile pipes with a diameter of 80 mm and a sheet of iron to make a door 5 mm thick.
Tools
To manufacture a structure from a gas cylinder, you will need the same list of tools as in the case of assembling a structure from sheets and profiles:
- Welding machine and electrodes;
- Grinder or grinder, metal discs;
- Measuring tools – tape measure, ruler, corner;
- Pipe bender;
Step-by-step instruction
- Using an iron sheet, a suitable blank is cut out and a baffle is welded on to create a second combustion chamber.
- Then a hole is made for a pipe with a diameter of 120 mm and a chimney with this diameter is welded.
- On top of the cylinder, which is now the combustion chamber, blanks from round or profile pipes, in which the air is heated.
- Then the hinges are welded and the oven door is installed.
Improvement and modernization
Homemade Buleryan is not attractive appearance, so it can spoil the atmosphere in the room. Often, in order to correct this problem, the structure is refined and modernized by welding designer parts or various forged elements onto the skeleton.
The main thing to understand is that high-quality air circulation is very important in the operation of this system, so all openings must be open:
If the heating system is installed in a garage or greenhouse, then it is not necessary to improve it, it will not spoil the aesthetic appearance, and efficiency can be lost if the furnace is unnecessarily modernized.
Distributing heat throughout the rooms of the house
The use of Buleryan in multi-room buildings is ineffective because it is not capable of heating large areas. Most often, such systems are used in greenhouses, garages and sheds. But some owners also install this stove in their dachas, using warm air distribution to several rooms in the house. In this case, the same wiring system is used as when installing a fireplace:
You should remember about the quality of ventilation in this case; it is best to install the warm air distribution by a specialist in this field.
Improved appearance
By far the best way to improve and give an aesthetic appearance to Buleryan stoves is brick or stone masonry. The main thing is to leave all the holes open, both for the entry of cold and the exit of hot air.
All stove channels are hidden
You can decorate the interior using bricks and a stove without embedding the structure itself inside the masonry, as was done in this solution:
Brick wall
In European countries, this stove is used as a decorative element, which can also be done in the case of a homemade structure by building it into a fireplace or covering the heating system with brickwork, as in the photo below:
Buleryan under the fireplace
Converting a potbelly stove for liquid fuel
Breneran is a converted potbelly stove, a stove with pipes welded on top to heat the air in the room. The alteration occurs in the same way as the production of Buleryan, which is described in this article above.
Water circuit installation
In order to increase the efficiency of the heating system, a water kennel is welded inside the solid fuel stove, which, when heating the water inside, allows heating the radiators installed in the room. This type of firebox is very popular in rural areas, as they are solid fuel boilers long burning. The disadvantage of such boilers is that the pipes inside are heated aqueous liquid, take away some of the energy and lower Furnace efficiency, but if you need to heat a large number of rooms, then it will be more effective solution problems than heating them with warm air.
In order to correctly install the water circuit, it is best to call a specialist or buy a ready-made system, into which you can then install the water heating system yourself. Since the correct functioning of this type of heating requires a structure made taking into account certain tilt factors, the installation of a pump and a condensate outlet is necessary, it is best to entrust the installation of the water circuit to a professional.
But if you still decide to implement this heating system yourself, then below is suggested correct scheme water heating circuit:
Operating rules
Despite the simplicity of execution, you need to heat the Buleryan stove using certain knowledge and rules:
- For ignition, it is necessary to use exclusively dry and solid fuel, wood chips, pressed cardboard, and small boards.
- Do not clean out the coal and ash formed after ignition; their layer will protect the metal bottom from burning out;
- The main fuel loading occurs after most of the ignition has burned out, namely 2/3 of the total initially loaded fuel;
- You should not use wet firewood and coniferous wood - they will cause plaque to form on the walls of the stove and chimney, reducing the efficiency of the heating system;
- Experts do not recommend using coke and coal, as they burn too quickly and do not allow the air to warm up enough;
- Maximum efficiency is achieved through a closed damper and blower: convection processes in this case begin to work more efficiently;
If all these operating rules are taken into account, the outer casing will not heat up to high temperatures, and the air leaving the pipes will reach its maximum temperature in less time.
Conclusion
The heating system of the building using a long-term combustion furnace, called Buleryan, involves saving fuel while providing high-quality heating of the air inside the building. Such stoves are very effective in country houses, garages, greenhouses and agricultural buildings. They are quite safe to use. But the main advantage of these heating systems can be considered that the manufacture of a Buleryan stove is possible at home, without the use of complex technologies and expensive materials.
What will you make buleryan from?
Profile pipeGas cylinder
←Previous article Next article →Externally, the Buleryan stove resembles a potbelly stove with a fancy design. But the efficiency of this device is much higher, and the scope of application is wider.
Industrial production models are quite popular, but by making a Buleryan stove with your own hands, you can provide heat for a garage, outbuilding, or even a small house. Agree, the idea is interesting, and the savings on purchasing a new unit are quite noticeable.
In the prepared article you will find all necessary information for the construction of a heating unit. We will tell you how the Buleryan stove works and works, describe what materials and tools will be needed during the work, and also provide step by step instructions for making homemade products.
In addition, the article provides practical advice for chimney installation and maintenance heating installation. By following our recommendations, you can organize efficient and safe heating of a small room.
The principle of Buleryan’s work is ingenious in its own way. It combines the operating features of a long-burning furnace and convection of air masses through special tubes. These elements allow you to immediately visually distinguish the Buleryan stove from other devices of this type. The combustion chamber is designed in such a way that the fuel burns slowly.
The highlight of the design is the air tubes. They are integrated into the combustion chamber body and form part of it. The upper and lower sections of these tubes remain open.
If desired, the side walls of the Buleryan stove body can be made double by welding another sheet of metal on top to reduce heat loss
Cold air enters the air ducts from below, heats up quickly enough and exits through the upper openings into the room. Convection is carried out constantly, so gradually all the air in the room warms up well and quickly to a comfortable level.
Using tubes as the body of the device has another undoubted advantage: constant air circulation does not allow the surface to heat up to a dangerous level. As a result, it is much more difficult to get burned by touching the Buleryan stove than by contact with the surface of a potbelly stove.
In this way, you can heat not only air, but also water. To do this, you will have to connect the Buleryan stove to a heat exchanger through which it will pass.
The movement of air masses through the air ducts located on the side walls of the case occurs naturally: cold air enters from below, hot air moves upward
It is worth noting that to ensure the fuel combustion process in such a device, ignition is first performed, during which firewood is added gradually in small portions until the chamber is filled. After this, all that remains is to load firewood into the firebox every 12 hours.
The firebox carries out a process of slow combustion of wood, which takes place in two stages, as in other boilers of this type. At first, the fuel burns slowly with little oxygen. This process produces a flammable gas. It then connects with air.
The second stage is the combustion of this gas-air mixture, which releases a large amount of thermal energy.
Factory-made ones are characterized by high efficiency, since they allow you to get much more heat than with regular wood combustion. The efficiency of the Buleryan furnace thanks to the implementation of this technology is about 80%.
The productivity of even small models can exceed five cubic meters of warm air per hour, which is quite enough even for spacious rooms.
How does it work
The Buleryan stove consists of the following elements:
- a combustion chamber formed from bent tubes and strips of metal;
- secondary combustion chamber;
- back wall;
- front wall;
- fuel loading door;
- chimney pipe;
- ash pan;
- injector;
- chimney damper;
- power regulator;
- blower, etc.
The back wall is made of two sheets of metal separated by a small space. This protects part of the device body from heating up to high temperatures, and also increases the overall efficiency of the furnace. In the secondary combustion chamber, combustible gases formed during the smoldering of fuel in the primary section of the combustion chamber are burned.
Before starting work on making a Buleryan stove with your own hands, you should study its design and operating principle in detail (+)
On the front wall, in addition to the door, there is a handle with which you can regulate the amount of air entering the chamber. The chimney damper performs similar functions. You can use only one of these elements to control the combustion process, or use them simultaneously.
Dimensions of the ash pan, i.e. The containers for collecting ash are small, and this is quite justified. If the Buleryan stove is started correctly, then during operation the wood will burn almost completely, so a minimal amount of ash will be produced or there will be no ash at all.
Several important elements. It is assembled separately and then hung using welded metal hinges.
To increase the efficiency of the device, some manufacturers cover the Buleryan stove with a double casing. This is not a mandatory, but desirable element in the design.
If there is enough stock sheet metal, after completing the main assembly of the furnace, you can weld curved elements on top of the tubes, which will hide the tubular “ribs” and make the device safer.
DIY process
Considering the not very simple design of the device, it makes sense to draw up a drawing of the Buleryan stove in advance or find finished project, for example, on the Internet. You will have to do a lot of cutting and welding of sheet metal, which requires a welding machine and skills to work with such equipment.
To successfully cut metal, experts recommend using patterns.
To cut sheet metal parts, it is recommended to use cardboard patterns to accurately maintain the dimensions and configuration of the elements
The main material for the manufacture of the Buleryan stove is sheet metal 5-6 mm thick and metal pipes with approximately the same wall thickness and an outer diameter of 50-60 mm.
To give the tubular elements the desired configuration, it is advisable to use. To check the position of individual elements relative to each other, use a construction hydraulic level.
For the normal flow of the work process, you will need a number of other devices and materials:
- electrodes for the welding machine;
- roulette;
- marker;
- clamps;
- square;
- ruler;
- Grinder.
They usually start with cutting metal and cutting pipes. Then the remaining metal is removed, and individual elements welded together, gradually assembling the oven.
Needs cutting required amount tubes (for example, eight pieces, depending on the specifics of the project) 120 cm long. Using a pipe bender, they are bent to a radius of 225 mm. The elements of the rear and front walls, doors, regulators and strips for the housing are sequentially cut out of a sheet of metal.
Tubes for the side walls of the Buleryan furnace must be laid on flat surface and fix their position with wooden beams
The remaining metal is used for the manufacture of door elements, ash pan, pipes, etc. Blanks for the V-shaped chamber are made separately. The metal strips for the body are cut with a width slightly larger than the outer diameter of the tubes. Oval cuts are made at the ends so that they can be welded tightly to the tubes.
The side air ducts are connected at the points of contact by welding, then I install a V-shaped pan inside to separate the secondary combustion chamber
The inlet and outlet pipes can also be made from strips of sheet metal, bent into a ring. An alternative is to simply cut pieces of suitable length from the metal pipe. But its diameter must be larger than that of the structure used for the device body.
Assembly of the device begins with tubes. The correctly bent elements must be laid in a checkerboard pattern so that the back side of the structure is at the bottom and the front side is at the top.
So that the pipes are in correct position, use wooden blocks with a thickness equal to the outer diameter of the metal elements.
Bent strips of metal are applied to the side tubes and first welded in some places, and then a continuous weld is made
If the pipes are cut and bent correctly, it will be possible to lay out such a “pyramid” on a level base without any problems. After this, the pipes should be welded to each other at the points of contact.
The resulting structure can now be turned over and a V-shaped pan can be welded in the space between the “ribs”. It will separate the primary combustion chamber from the secondary. An injector should be made in one of the front wall tubes to supply air to the secondary combustion chamber.
A hole is made in the side tube into which a narrow injector is welded to ensure air flow into the second section of the combustion chamber
After this, you can continue to form the stove body by welding the previously cut strips of metal to the ribs. The optimal option is when approximately two-thirds of the pipe diameter is recessed into the body, and a third of these elements remains outside. You will have to tinker with the manufacture of the front wall of the stove.
In the front wall of the Buleryan furnace, a fairly spacious hole is made for the loading door, to which a small side is welded
In the blank for the door, first make a hole for the blower. A pipe is welded to it, in which a damper will be installed to regulate the flow of air entering the primary combustion chamber.
For the damper, you need to cut out a round part, the diameter of which exactly matches the dimensions of the pipe. A pin is welded to the damper. After this, a hole is made in the pipe along the axis into which this pin is inserted.
If the elements of the Buleryan stove are cut and laid correctly, the finished body will look neat. During assembly, you need to control the position of each part using a building level
A hole is made in the blank for the front wall for the door. A narrow strip of metal is welded to it around the circumference.
Two such strips of metal need to be welded to the door itself, one along the very edge, the other should be inside at some distance from the first. If everything is done in accordance with the drawings, then the “collar” on the front wall will fit exactly into the gap between the edges of the door.
Two sides are made on the round door, between which the side welded to the front wall of the Buleryan stove must fit exactly
It is recommended to lay asbestos rope in this space to ensure maximum tightness when closing the door. Now you need to weld its inner part to the door, as well as the hinges on one side and the eccentric latch on the other.
The eccentric lock ensures a tight fit of the door to the front wall of the stove for maximum tightness, which is important during long-term burning of wood.
A damper with a damper on the door of the Buleryan furnace allows you to regulate the amount of air entering inside in order to establish the optimal operating mode of the device
It is better for an inexperienced craftsman to order this element from a professional turner. Hinges and a metal pin for the latch are also mounted on the oven body.
Now a double back wall with a hole for the chimney pipe is welded. This element is first applied to the finished structure to make sure that its contours exactly match the outlines of the pipes fastened together.
To ensure that the dimensions of the door exactly match the parameters of the hole on the front wall, it is recommended to first weld all necessary elements door and “try on” the dimensions of the side of the loading opening for it
At this stage, you can cut off the excess without any problems. This also applies to other elements - before welding, they are checked for consistency and adjusted if necessary. Now the oven is almost ready. Four legs need to be welded to the body. They can be made from bent pieces of thick wire.
Manufacturing an eccentric latch for the Buleryan oven door requires great precision; it is better to order this element from a good craftsman
The legs are welded to the front and rear walls of the housing. The finished device is installed on a flat and durable base, covered with fire-resistant materials: asbestos, smooth slate, ceramic tiles, etc.
It would also be a good idea to protect the walls around the stove from exposure to high temperatures.
The legs for the body of the Buleryan furnace can be made from very thick wire or bent thin tubes. It is important to give the device stability and correct position
Now a pipe is attached to the chimney pipe and secured with a coupling connection. In this case, the pipes are installed in a position opposite the direction of gas movement, although the manufacturer recommends doing otherwise. It is recommended to insulate the chimney, for example, with mineral wool.
Metal hinges for the Buleryan oven door are not difficult to make yourself from available materials and weld in the required place
“Incorrect” installation is due to the need to protect the structure from resin, which is formed as a result of wood combustion. If this moment is not provided for, then the resin will flow out of the stove, and with such an installation it will remain in the chimney and gradually burn out.
Upon completion of assembly, the Buleryan stove is installed on a flat and fire-resistant base and connected to the chimney. In this case, it is necessary to comply with fire safety rules
Clogging with resin for the Buleryan stove is almost inevitable. Over time, resinous layers accumulate and clog the device. This is expressed in a noticeable reduction in the efficiency of its operation, a decrease in traction, and problems with the free movement of the gate. So it's time to start cleaning the oven.
A lightweight version of this cleaning is to heat the device with aspen firewood. Unfortunately, the practical benefits of such a measure are small and short-lived.
The best way to eliminate resin contamination is burning. To do this, the stove is heated strongly with the ash pan open, essentially calcining all the channels. As a result, the resinous deposits burn out.
Some craftsmen use oxygen to burn the furnace, bringing the nozzle of the cylinder to the opening of the ash pan. This is an extremely dangerous operation that violates fire safety regulations. Careless handling of an oxygen cylinder near an open flame may cause an explosion.
As fuel for the Buleryan stove, you can use not only firewood, but also wood waste (shavings) or. Important condition - low humidity fuel. The less moisture, the less resin is formed inside the stove, and the less often it will have to be cleaned.
During operation of the furnace, you need to select an operating mode in order to obtain maximum heat with minimal resin formation. If best option found, cleaning will only need to be done a couple of times during the heating season.

Buleryan solid fuel stoves continue to gain popularity. They differ high efficiency and the ability to quickly warm up rooms. Consumers can purchase ready-made units or try to assemble a Buleryan stove with their own hands. There is nothing complicated about this, because in its design it resembles the most ordinary pyrolysis potbelly stove. The only differences are in the housing, which is equipped with efficient tubular convectors.
Design Features
Assembling a Buleryan stove with your own hands is really very simple. But only for those who know how to handle tools and iron, and also have an understanding of the structure of solid fuel stoves. There are no particular structural difficulties here, but you need to remember that working with iron requires special care - it is not as malleable as wood. But the end result should be excellent heating unit, which will delight you with quick warm-up and long-lasting combustion.
The Buleryan stove, assembled with your own hands, is a traditional solid fuel unit that runs on wood using a gas generator circuit. That is, the wood burns here, releasing pyrolysis products, which are sent to the afterburning chamber and burned there with secondary air. Combustion products go up the chimney, escaping into the atmosphere and partially falling out in the form of condensation - we will tell you how to get rid of it with just one movement of the hand.
Our Buleryan potbelly stove consists of the following parts:
- The main combustion chamber is spacious, roomy, the firewood lies directly on the convection pipes;
- Afterburner chamber - located above the combustion chamber, it is a perforated or solid sheet of iron that separates the upper quarter of the entire internal volume;
- Tubular convector - a set of curved pipes, most of the area of which is in direct contact with firewood, coals and combustion gases;
- A loading door with a small blind flap - through it, firewood is loaded into the Buleryan oven, made by yourself. It also allows you to regulate the access of oxygen to the combustion chamber;
- A chimney with a slide damper and a chamber for collecting condensate - ensures the removal of combustion products and collects condensed combustion products for their subsequent removal.
Also in the design of the furnace there are tubes (injectors) for supplying secondary air - it is needed in the afterburning chamber for combustion of pyrolysis.
It was the simplicity of the Buleryan convection oven (also called the Breneran oven) that gave it its well-deserved popularity.
It is this unusual appearance that makes the Buleryan stove so extremely effective.
In order for you to experience all the delights of the Buleryan stove, we will tell you about its operating principle. We have already said that the pyrolysis reaction is used here. The burning of wood with a limited supply of oxygen looks like smoldering with the release of pyrolysis products. Entering upper chamber afterburning, they ignite and burn with the release of a large amount of heat - combustion is supported by small injectors built into two convection pipes.
The blower and gate valve are responsible for maintaining the pyrolysis reaction. They are responsible for limiting the supply of oxygen and slowly removing combustion products. Thanks to this, the heat is almost completely sent to the heated rooms.
Many users are wondering whether a potbelly stove or Buleryan is better and what to give preference to. The efficiency of a potbelly stove, including a pyrolysis one, will be lower. To increase efficiency, it will be necessary to retrofit it with additions that create convection. But the potbelly stove still won’t be able to catch up with the Buleryan stove, no matter how hard you try. Buleryan is the most efficient and advanced stove today, with an extremely lightweight design.
Buleryan during mining is not a solid fuel stove. But you can assemble it with your own hands, according to a similar scheme, by building homemade burner into the loading door (we wrote about assembling such a burner in our reviews). It is also possible to purchase already finished burner. But such a scheme will be justified only if you have access to inexpensive supplies of this simple fuel.
Making homemade Buleryan
This oven has wide scope applications. It is suitable for heating residential buildings, country houses and utility rooms. If you need a good stove for the garage, Buleryan will be a worthy solution - fast-acting and effective. Literally 15-20 minutes after ignition, a comfortable and warm atmosphere will be established in your garage.
The Buleryan stove, made by yourself, will delight you with its ease of operation and unpretentiousness to fuel. However, the logs for it must be dry (preferably no higher than 15% humidity), otherwise the pyrolysis reaction will occur with difficulty. High humidity firewood leads to a large number condensate Let's see how to assemble it with your own hands.
Drawing for assembling the furnace, materials and tools
We present you with a drawing with dimensions that we will use as a guide when assembling the Buleryan stove with our own hands.
Detailed diagram of the Buleryan stove.
During the development process, you can make your own changes if they seem necessary to you. For example, nothing prevents you from fitting a ready-made door here, so as not to have to worry about it self-assembly. Along with the drawing you will need the following tools:
- Hydraulic or manual pipe bender;
- Welding machine;
- Angle grinder for cutting steel;
- Grinding disc for correcting welds.
- Pipe with a diameter of 60 mm for the manufacture of a convector (heater) - the drawing shows pipes with a diameter of 50 mm, but then the convection will not be so intense. In this case, we advise you to focus on the area of the heated room;
- Sheet steel with a thickness of at least 4 mm - from this we will cut intermediate plates, as well as the front and rear walls;
- Chimney pipe with a diameter of 100-130 mm;
- Metal pipe to create a choke (blower) on the loading door;
- Hinges for the loading door, as well as secure lock with a safety handle for opening and closing;
- Materials for creating a slide damper - another handle with a small piece of sheet steel to block the chimney clearance;
- Metal pipe with a diameter of 15 mm for injection pipes.
An asbestos cord is also useful to seal the door. Don't forget to pick up good electrodes for welding metal parts.
You will also need thick cardboard, from which it is very convenient to make patterns for later cutting out metal - this way you will save time and nerves. By the way, some craftsmen make Buleryan stoves with their own hands from a square pipe. It turns out a little scary, but overall it works.
First steps
First, we need to make the frame of our entire Buleryan stove - it is an interweaving of curved pipes that form an air heater and the future firebox. Use a pipe bender and bend them to a radius of 225 mm. The length of each pipe is 120 cm - this is more than enough. The pipes are welded together with metal strips to create a stable base for our stove. There should be no holes on the sides, otherwise smoke will penetrate into the heated rooms.
Making an afterburner
The next stage of making a Buleryan stove with your own hands is creating an afterburner chamber. To do this, you need to take sheet iron and make partitions from it with recesses for the air heat exchanger.
Next, we weld the partitions from the inside to the pipes so as to separate about a quarter of the internal volume (or as indicated in the drawing). Please note that these partitions go to the rear wall, and they do not touch the front wall (secondary air injectors are welded into the first two pipes).
Pyrolysis products will end up here. And the combustion products will go to the back wall, where the chimney of the Buleryan stove is located.
We complete the assembly of the base
Now we need to cut from sheet iron two pieces forming the back and front walls of the Buleryan stove. But don’t rush to weld them - they still need work. In the back wall we make a hole for the chimney, focusing on the diameter of the chimney pipe.
After this, we move on to the front wall - here we need to make a hole for the insert. The door is made from a piece of pipe with a diameter of 350 mm. And here you will have to suffer.
The whole point is that the door should tightly close the inlet of the firebox. We weld a part of a pipe with a diameter of 350 mm to the front wall of our Buleryan stove, which we assemble with our own hands - it protrudes slightly, as in the picture. Next we make the door itself - it will be double-layered, inner part will go inside the loading hole, and the outer one will cover it from the outside.
We make a hole in the door of the Buleryan stove for the choke. Its dimensions are indicated in our drawing. It is a small section of pipe in which a damper rotates on a metal loop - it should completely block the gap. To prevent the loop from rotating under its own weight, we press it with a spring. It is also necessary to make a reliable lock to secure the loading door.
Fiddling with doors, throttles and dampers when assembling a Buleryan stove with your own hands is the most problematic, because working with small parts is always more difficult than working with large ones. But if your hands grow from there, you will cope with the task relatively quickly.
Making a chimney
If you think that the chimney for the Buleryan stove, assembled with your own hands, is a piece of pipe, then you are completely wrong. We will make a T-shaped chimney with a slide damper for our stove.
Unlike a throttle, the gap here is not completely blocked, but only 3/4 of the maximum diameter of the chimney - this is exactly the damper that will need to be cut out and installed in the outlet (horizontal) pipe.
We weld a vertical section to the horizontal chimney pipe of the Buleryan stove. Smoke will escape through its upper part, and condensation will accumulate in the lower part (it will definitely happen). To make getting rid of it more convenient, weld it to the bottom ball valve. Just one movement of the hand - and all the accumulated condensate will drain into a previously placed container, as we promised earlier.
Final stage
By the way, our DIY Buleryan stove is almost assembled. We already have:
- Main body with air heater;
- Two walls with doors and a throttle;
- Chimney with throttle valve.
It's time to weld all the components into a single whole. Once again we make sure that the seams between the metal plates and the convection pipes are tight, and then we proceed to install the front and rear doors.
Remember that the afterburner should be located in the upper rear part - do not mix it up.
After welding the walls, we check the fresh seams. At the next stage, we arm ourselves with an angle grinder and carefully grind the seams to make them more neat. Finally, we connect the chimney and begin painting the Buleryan stove using heat-resistant paint. Part of it will subsequently burn (for example, on the front door), but the upper part will remain intact, since convector pipes do not heat up to the highest temperatures.
The final stage includes the installation of a self-assembled Buleryan stove on a metal or brick pedestal. Optimal height the location of the lower part of the convection pipes is 20-25 cm from the floor level. Next, we install the chimney and load firewood into the firebox. At the first stage of ignition, the throttle and gate valve are fully open - the firewood should ignite completely. After this, we close the gate valve and the throttle, which is why the Buleryan stove will switch to the pyrolysis combustion mode.
Adjustment of the combustion intensity is carried out using the throttle and slide valves - here you will need a little practice to achieve optimal results. In addition, you can upgrade the Buleryan stove, assembled with your own hands:
- Convert the air heat exchanger into a water heat exchanger and connect it to heating system– you will get a powerful, productive wood-burning boiler;
- Connect the convector inputs with a pipe and connect a powerful blower fan here. Similarly, combine the outputs of the heat exchanger and connect to them flexible pipes and distribute heat to neighboring rooms - you get an air heating system;
- Install the Buleryan stove in small room(the size of a toilet) and from this room distribute pipes with hot air to other rooms - another way to organize air heating.
It may take you up to several days to make a Buleryan stove with your own hands, but overall the results should please you.

In the world of autonomous heating, this is not the last place useful device like the Buleryan stove, also known as Breneran. Roughly speaking, it consists of a firebox, to which a series of bent tubes are connected. This design allows you to burn wood and other types of solid fuel with very high efficiency. The cost of industrial models starts at two hundred dollars and increases depending on the size of the firebox. Although the design of such a stove is somewhat more complicated than that of a conventional potbelly stove, many craftsmen have managed to make a buleryan with their own hands.
How does this design work?
Buleryan can be called a very successful hybrid of a potbelly stove and wood stove long burning. The device operates using the principle of forced convection. A series of curved tubes are connected to the firebox at the top and bottom. Cold air enters the lower openings, which quickly heats up since the pipes are in direct contact with the firebox. Hot air enters the rooms through the upper openings. Its temperature is so high that it allows you to heat not only one specific room, but even two-story house. There is also the possibility of combining the Buleryan stove with a water heating circuit. At the same time, the surface of the device itself remains not too hot and does not pose a danger to others.
Thanks to a number of simple adjustment devices, the oven can operate in two modes. First, the stove heats up quickly, and then the resulting heat is evenly distributed throughout the room. At the second stage, the oven switches to slow burning mode. In the beginning, fuel needs to be added quite often, but once the stove warms up, the firebox can be loaded only twice a day, i.e. every 12 hours.
Firewood burns in the firebox, and the products of this process flow through convection pipes into the secondary combustion chamber. Here the gas-air mixture is burned at very high temperatures, which provides the device with an efficiency of around 80%. Next, the hot air is distributed throughout the room through convection pipes.
The process of operation of the Buleryan furnace is clearly presented in the video:
Diagram of the classic "Buleryan"
To successfully make such a stove yourself, you should first study its structure. This is an all-metal structure consisting of a firebox and a number of bent metal tubes adjacent to it. There is a door in front through which fuel is loaded, as well as a power control device with which you can change combustion modes. A secondary combustion chamber is equipped in the firebox and a pipe is installed under the chimney.
This diagram shows in detail the structure of the Buleryan furnace. Main distinctive feature designs - a series of curved hollow tubes that are connected to a two-chamber firebox
To increase the efficiency of using the Buleryan stove, it is recommended to thoroughly insulate the chimney, for example, with a layer of mineral wool at least 3 mm thick.
Of course, you will need a blower through which the air necessary for combustion of the fuel will enter the firebox. You can arrange a small ash pit, although the process of slow burning produces almost no waste. The double rear wall makes the device even more efficient. Some models use a two-layer casing for this.
Step-by-step manufacturing instructions
To make a Buleryan oven with your own hands, you need to stock up metal pipes with an outer diameter of about 50-60 mm, as well as sheet metal. To endure high temperature combustion, it is recommended to use steel sheets with a thickness of 4-6 mm. Besides welding machine and a standard set of tools you will also need a pipe bender.
- Production of bent pipe sections.
- Manufacturing of a device for smoke removal and condensate collection.
- Manufacturing of dampers for vent and outlet.
- Making a door for the combustion chamber.
- Weld a frame of bent pipes and install a partition in it.
- Welding metal sheets in the space between pipes.
- Installation of a door with a lock.
- Manufacturing and welding of metal legs.
Eight identical sections, about 1.2 m long, should be cut from the pipe. Using a pipe bender, they are bent with a radius of 225 mm and placed in a checkerboard pattern.
To make the hollow pipes needed for the furnace, you need to prepare eight pieces of pipe, each 1.2 meters long, and bend them to a radius of 225 mm using a pipe bender
To remove smoke, as well as accumulated moisture, a T-shaped device is made, through which the smoke will go up into the pipe, and the moisture will flow down. To remove moisture, a special tap is installed below. The moisture removal valve should be opened only for these purposes and then closed so as not to impair traction.
Left: device for removing smoke from the oven T-shape designed not only to remove smoke, but also to collect condensate.
Right: The condensate drain valve is located at the bottom of the smoke exhaust and condensate collection device. It should be opened only when necessary, so as not to impair traction.
To remove smoke from the stove, a special damper is made, which is also used to regulate draft.
The damper for regulating the power of the stove is made with a special hole that allows you to change the draft, but does not allow you to completely block the chimney
For the blower, which is located on the front door, you should make a blind damper. To ensure that the flaps are securely fixed in the correct position, a spring is used.
The flap for the blower, which is located on the front door, must be made blind. This will ensure maximum efficiency of the stove in slow burning mode
The most difficult element of a homemade Buleryan is, perhaps, the front door. It should close almost hermetically. The better the door fits to the stove, the more efficiently Buleryan works.
From the pipe large diameter two rings are made that fit almost tightly into each other. To do this, cut two 40 mm pieces from a pipe with a diameter of 350 mm. One of the segments is cut and unfolded. After this, the front side of the stove is made using a ring of smaller diameter.
In the front wall of the furnace it is necessary to make round hole, to which a metal ring is welded. This element is necessary to ensure that the door closes as tightly as possible.
The second ring is used when installing the door; it is welded to a circle of sheet metal.
Two metal rings, the diameter of which is slightly different, are welded along the edge of the oven door. They are sealed with a special gasket made of asbestos cord
Then another ring is welded onto the door, which should be slightly smaller than the diameter of the ring placed on the front side of the stove. A sealing asbestos cord is placed in the gap formed between the door rings and the damper is mounted.
To complete the installation of the front oven door, it is necessary to weld the blower pipe with a damper to it. The damper is equipped with a spring for a tighter fit
Now we should return to the bent pipes. It is necessary to make holes in the first two pipes and weld injection tubes into them. These are small metal elements with a diameter of 14-15 mm and a length of about 150 mm. They are necessary to ensure the connection of the convection elements with the firebox.
Special injectors should be inserted into the first two hollow pipes of the furnace, which will ensure air contact with the combustion chamber
A stove frame with a partition is made from pipes. For the partition, it is recommended to use sheet steel at least 6 mm thick.
For the furnace partition, steel 6 mm thick is used. To avoid having to “guess” with the dimensions, first make cardboard patterns
After this, the gaps between the pipes should be closed with strips of sheet metal, and the back wall should be welded, thus forming the furnace body.
The furnace body is formed from pieces of metal, which are welded in the space between the hollow pipes. Cardboard patterns are also useful for making them.
In order to accurately cut out the elements of the partition, back wall and strip of metal, it is recommended to first make cardboard patterns.
It is recommended to make a special lock for the door. It is an eccentric that fixes metal loop located on the wall of the stove. With further scrolling, this device ensures the tightest possible fit of the door to the stove. To make such a device, you will need to perform a number of turning and milling operations.
Making a lock for an oven door is not easy. Inexperienced craftsmen should seek help from a professional turner or milling machine
All that remains is to make the hinges and hang the door, as well as cut, bend and weld the legs of the stove.
Furnace legs can be made from suitable thin tubes, giving them the required shape using a pipe bender or available tools
The manufacturing process of Buleryan can hardly be called simple; an ordinary potbelly stove is much easier to make. But ease of use and high efficiency fully justify the time and effort spent.
